19/100 and 0.19 are the answers.
This can be solved by ratio and proportion. The first condition is
3 1/2 hours is to 1/3 tank of gas
The proportion relation is
3 1/2 : 1/3 :: x : 1/2
where x is the number of hours that Tanya can drive
7/2 / (1/3) = x / (1/2)
Solving for x
7/6 = x/2
x = 14/6 or 2 and 1/3 hours<span />

Answer:
-2
Step-by-step explanation:
When you're looking for f(3), you want the y-value that corresponds to the x-value of 3. Find it by locating 3 on the x-axis. Then follow the vertical grid line to the point where the function value is shown. From there, identify the y-coordinate of that point. That y-coordinate is f(3).
f(3) = -2
__
The open dots at the ends of the curves at x=3 mean the function is not defined at those points: (3, 1) or (3, -9). The solid dot at (3, -2) tells you the function value at x=3 is -2.
The first step to finding your answer is to remove the first set of parenthesis.
3 x
x ( 2 x
)
Then remove the second set of parenthesis.
3 x
x 2 x
Now multiply 3 and 2 together
6 x
x
In order to multiply terms with the same base,, you must instead just add their exponents together. This will look like the following:
6 x
This means that the answer to your question will be 6 x
when put in scientific notation.

A positive derivative means that the function is increasing.
